Research On Workflow Model Supporting Dynamic Change

According to the analysis of domestic and international research on workflow, the research on WfMS that supported dynamic change has become the hot spot of this domain. The most of existent WfMS can not estimate the relationship of workflow data automatically. Therefore it is inefficient and venturesome to modify the workflow instance. Point to these defects, the DOAWfMS (Dataoriented Adaptive Workflow Management System) is been proposed. The DOAWfMS extends the interface of tradition WfMS's exception handler, supports dynamic modify, and it can check workflow data's relationship real-time. And so the DOAWfMS is more efficient and reliable on dynamic modifying than other WfMSs. The DOAWfMS defines the dependence among workflow data, and illustrates this definition with Petri Net, and offers a detect algorithm for it. At last, the validity of algorithm is proved by the Petri Net theory and an example.
